Abstract
A brazing pin for use at soldering for example a cable lug and a railway rail consists of a pressed or turned main part (11) with a stud (13) at one of its ends, a cap (14) of solder alloy material pressed on the stud and flux (15) in the space between the cap and the stud. The outer diameter of the cap (14) corresponds to the outer diameter of the main part (11), whereas its inner diameter is slightly smaller than the inner diameter of the stud (13), so that a hermetic enclosure for the flux is obtained.
Description
The present invention relates to the manufacture method of brazing pin, be used for for example the cable connector lug being soldered to rail, relate to this brazing pin in the present invention.
When for example cable connector lug and rail fuse, the so-called brazing pin of known use.This brazing pin also can be used for other connector and be used in and require the surface of metal object and any kind of is fused.When cable connector lug and rail or other metalwork are welded, brazing pin is inserted into the medium pore of cable connector lug, be close to rail, subsequently heavy current by brazing pin and rail, produce a luminous arc, in the solder alloy fusing of brazing pin end, fill the hole of cable connector lug, the cable connector lug couples together by fusing and rail simultaneously.
In early known brazing pin, inserting of solder alloy is contained in of brazing pin, subsequently relatively thinner solder alloy lid be added to insert on.Put the scaling powder that correct fine weldering is needed in the little space between inserting and covering.
But the main body of brazing pin preferably by the brass manufacturing so that favorable conductive.This main body can be provided with annular groove suitably, and the part of this main body before groove becomes the coupling part with solder alloy after welding, helps the hole of filling cable connector lug.
The manufacturing of this brazing pin is somewhat expensive, because the main body of the brazing pin of brass is at first wanted turning, suppresses or casts out, and scolder is inserted and must be installed on the main body of brazing pin subsequently, and again through pickling, turning and cleaning, the bonnet of gland that has scaling powder is on inserting.Except making costliness, the lid that the iron spot of existing brazing pin has scaling powder in addition is not to cover airtightly, causes the scaling powder possibility moisture absorption, and brazing pin can not be used.
Method according to the invention provides a kind of new manufacturing brazing pin is characterized in that:
The main body machined of described brazing pin, preferably turning or suppress, a plush copper is located at the one end,
Hollow cap machined with heavy wall of solder alloy is preferably colded pressing or turning goes out, and the external diameter of described lid is suitable with the external diameter of described main body, and the internal diameter of described lid is slightly littler than the external diameter of described plush copper,
Described lid filling scaling powder and
Inside has the lid of scaling powder to be fitted in the plush copper of described main body.
The brazing pin of Zhi Zaoing is very simple in this way, and is more cheap than the manufacturing of above-mentioned common brazing pin, and lid is airtight, because it is with thicker material manufacturing, and the diameter a little littler than plush copper arranged, therefore available interference fit.
The present invention also provides a kind of brazing pin, be used to weld for example cable joint and rail, it is characterized in that, the end of the main body of described brazing pin is provided with a plush copper, by the lid of the heavy wall of solder alloy system, the external diameter of its external diameter and described main body is suitable, and internal diameter is slightly littler than the internal diameter of described plush copper, described lid is press fit on the described plush copper, and described scaling powder is located in the described lid.
Describe the present invention with reference to the accompanying drawings in detail, in the accompanying drawing:
Fig. 1 illustrates the schematic diagram that the part of the brazing pin of prior art is analysed and observe;
Fig. 2 shows the schematic diagram that the part of brazing pin of the present invention is analysed and observe.
Common brazing pin shown in Figure 1 for example has the main body 1 with the brass of turning or compacting.Columniform main body 1 is provided with cannelure 2, its objective is the joint-cutting that uses brazing pin as when welding, the passback of also restriction heat or pass to the left-hand component of main body.
What the front end of main body 1 (among Fig. 1 the right) was provided with solder alloy inserts 3.Diameter 3 is contained on the main body 1 than slightly little the inserting of main body 1.Be covered with thin lid 4 before 3 inserting by solder alloy system.A certain amount of scaling powder 5 is filled out in lid 4, lid 4 is covered insert on 3 subsequently.Because at the deformable sheet materials of lid in 4, lid 4 is than being easier to and inserting 3 disengagements, and be not inserting to encase gas-tightly.
The rear end of main body 1 (Fig. 1 left side) is provided with hollow handles knob 6, wherein inserts and fixed an one metal wire 7.Wire 7 is as the alive joint of brazing pin, and can be by transmitting certain energy can melt so that process is ended when heat increases.
Use brazing pin in when welding, main body 1 fusing of the right of groove 2 or the brazing pin in the place ahead inserts 3 and cover 4 and become filler.
Correspondingly, have a main body 11 according to brazing pin of the present invention (Fig. 2), groove 12 handles knob 16 and wire 17.Corresponding parts have same effect among these parts and Fig. 1.Can certainly be with not being with brazing pin wiry.
During fabrication, main body 1 is provided with plush copper 13,11 one-tenth of this plush copper 3 and main bodys are whole, is same material, just brass material.Lid 14 is preferably colded pressing by solder alloy and is formed.Other manufacture method can be with turning or casting.The material thickness of lid 14 is greater than the thickness of the lid 4 of prior art shown in Figure 1.Lid 14 external diameter is suitable with the external diameter of main body 11, and covers the external diameter that 14 internal diameter is slightly smaller than plush copper 13, is interference fit between covering 14 and protruding 13.Size can for example be: main body and to cover 14 external diameter be 8mm, the diameter of plush copper 13 is 4.5mm, and covers 14 internal diameter and the external diameter difference of plush copper 13 is 0.05-0.15mm.Also can make the brazing pin of other size.
Before covering on the plush copper 13, in lid, add a certain amount of scaling powder 14 to lid 14.Since have above-mentioned shown in and the structure of explanation, after lid 14 installs on the plush copper 13, scaling powder with add certain overvoltage.
Is the same according to the effect of brazing pin of the present invention with known brazing pin.Total difference is that brazing pin of the present invention is simpler, makes more cheaply, is that the lid 14 in unique solder alloy source can airtight mode be fixed on the plush copper 13 in design.
